Iritis presumed as secondary to disseminated coccidioidomycosis

BackgroundCoccidioidomycosis is a systemic disease caused by a fungus found in soil and transmitted through inhalation. It is prevalent in western and southwestern United States, Mexico, and South and Central America. Results of skin testing, serologic testing, and tissue cultures confirm the diagnosis. Coccidioidomycosis can manifest in various ways: the infected individual may present asymptomatically, with an acute respiratory infection, or, in more severe or chronic cases, with a multiorgan presentation. Ocular involvement may include anterior segment, posterior segment, or extraorbital involvement.Case ReportA case concerning a patient with iritis presumed as secondary to disseminated coccidioidomycosis is discussed. The patient initially presented to our clinic with signs and symptoms of acute, unilateral iritis and a recent history of iritis in the contralateral eye. The active inflammation was treated topically with Pred Forte and cyclopentolate and resolved without sequelae. Because the presentation was bilateral with an asymmetric timecourse, laboratory tests were ordered to rule out systemic association. Because all tests yielded negative results, the known history of disseminated coccidioidomycosis was presumed to be the etiology of this iritis.ConclusionAlthough eye findings are rare, disseminated coccidioidomycosis is an important differential to consider when a patient presents with uveitis. For this reason, awareness and recognition of ocular signs and symptoms of this disease is significant in proper patient care and management.
